ISPCONFIG3 with 2 NICS (one WAN, one LAN) DNS problems.

I recently setup a fresh install of ISPCONFIG3 with 2 NIC's. One NIC has the WAN IP and the other is a LAN IP that I planned to use for faster throughput to copy files back and forth. The problem is that after installing all the files ISPCONFIG/centOS 6.3 wanted to use the non-broadcast IP's to resolve DNS etc.

I have removed the LAN IP from /etc/hosts.conf and only have the WAN IP there as per ISPCONFIG3 install docs but it keeps overwriting with the LAN IP first (as the first nameserver) on reboot.

/etc/named.conf
I also edited this file and changed all the "any" to the actual WAN IP for the listen ports & allow query.
